Minor MLB Transactions: 8/27/17

The Reds selected the contract of right-hander Tyler Mahle before Sunday’s game against the Pirates and optioned fellow righty Luke Farrell to Triple-A Louisville (updated depth chart). The 22-year-old Mahle, who made his big league debut with a start on Sunday, earned his way to the majors with a combined 2.06 ERA, 8.6 K/9 and 1.9 BB/9 in 144 1/3 innings between the Double-A and Triple-A levels this season. Baseball America (No. 78), FanGraphs’ Eric Longenhagen (No. 85) and MLB.com (No. 86) each regard Mahle as one of the sport’s 100 best prospects. The 2013 seventh-round pick has a mid-rotation ceiling, per MLB.com, which notes that he’s a “command and control specialist” who brings a low-90s fastball that can touch 96 mph and average secondary offerings to the table.
